Page content keeps disapearing

Hi all, so I have an issue with a page on my site “My Portfolio” all that is on it is one line of text and then a gallery using the standard wordpress tiled gallery. It doesn’t show, all it says is “No Results Found” I have deleted the page and all images associated with it and re uploaded them still to no avail. I have no coding experience so if you could give me a step by step to fix that would be great. This is the Offending page if you want to take a look.

Thanks for any help.

Jeremy
